Abstract The Schrattenkalk Formation represents a complete succession of Lower Cretaceous shallow-water carbonate platform series cropping out in the Alpstein massif north-eastern Switzerland. is traditionally divided into two sedimentary units, “Lower” and “Upper” Schrattenkalk, separated by more marly Rawil Member. habitually dated to late Barremian, while Member are early Aptian. New field o...

The Late Triassic age Blomidon Formation consists nearly entirely of massive gypsiferous mudstone and sandstones arranged into distinctive sand patch cycles, many of which show various salt dissolution features. Identical Late Triassic, cyclical, largely clastic facies are widespread in Morocco, on the conjugate margin to Nova Scotia, where Blomidon-like strata frequently pass in the subsurface...

this study shows that ichonology can be used to refine sequence stratigraphy as well as to interpret the depositional environment of the kalat formation (upper maastrichtian) in the central kopeh- dagh basin (ne iran), dareh-gaz section. field studies and petrography of these deposits led to recognize four lithofacies and nine subfacies that formed in the tidal flat (lithofacies a), lagoon (lit...

The Sawtooth Fault in central Idaho, USA, is a range-bounding normal fault with Late Pleistocene–Holocene scarp near the up-valley ends of several range-front lakes. Cores from Redfish Lake, which spans fault, exhibit evidence catastrophic sediment re-mobilization two sequences consisting variably intraclastic mud-clast conglomerate, massive homogenite, and graded silt clay. Event strata younge...

Understanding how fault systems interact and transfer strain over seismogenic timescales (seconds to ka) requires temporal records of past ruptures along adjacent intersecting networks. Here we document the record Late Holocene as recorded in geomorphology alluvial deposits Ash Hill fault, Eastern California Shear Zone (ECSZ). We leverage a multi-faceted approach evaluate relative timing those ...

[1] A high-resolution stratigraphic image of a flume-generated deposit was scaled up to sedimentary basin dimensions where a natural log hydraulic conductivity (ln(K)) was assigned to each pixel on the basis of gray scale and conductivity end-members. The synthetic ln(K) map has mean, variance, and frequency distributions that are comparable to a natural alluvial fan deposit. A geostatistical a...

A hierarchical geostatistical analysis is conducted on a high-resolution, multiscale hydraulic conductivity (lnK) map, created by scaling up an experimental stratigraphy. Unlike a previous study which evaluates lnK variograms within individual depositional environments, this study analyzes deposits (or samples) that incorporate multiple depositional environments. Based on conductivity cutoffs s...
